orphaned?? tmp files

Given the below information, is it reasonable to assume that files in pgsql_tmp dated prior to 10 days ago can be
safelyremoved?

That listing doesn't show anything in pgsql_tmp ...

What the listing looks like to me is a tablespace containing a few
tables that haven't been touched in awhile.  Whether they're still
referenced from anywhere is not apparent from this data.
